Set of 2 Replacement Discs for Roller Sharpener, Replacement Discs for Rotary Knife Sharpeners, 400 and 1000, Round Sharpening Stone

【400# Grading + 1000# Grading | Coarse and Fine Sharpening in One Step】This kit includes two sharpening wheels: a coarse (400#) wheel and a fine (1000#) wheel. The coarse (400#) wheel quickly removes chips, nicks, and rust, effectively restoring the blade's shape. The fine (1000#) wheel is used for precise polishing and deburring, strengthening the blade's edge. This allows you to perform complete sharpening, from roughing to polishing, in a single pass. 【High-Strength Materials | Long-Lasting Sharpening Performance】Made from high-quality materials, these roller sharpening wheels offer exceptional hardness and wear resistance, ensuring consistent sharpening performance over the long term. Their robust construction withstands prolonged and repeated sharpening without warping, eliminating the need for frequent disc changes. An ideal solution for extending the life of your tools. 【Standard M12 Thread | Compatible with Roller Sharpeners】The sharpening stone's thread has a diameter of 12 mm (metric M12 thread) and is therefore compatible with most standard roller sharpeners. Please carefully measure the thread diameter of your sharpener before purchasing to ensure secure installation, optimal sharpening, and safe use. 【No Water or Electricity Required | Fast Sharpening Anywhere, Anytime】This roller sharpener requires no water or electricity; it is entirely manual. This allows you to maintain your knives anywhere, anytime: in the kitchen, outdoors, in the workshop, etc. Its simple and intuitive use requires no special knowledge, allowing you to sharpen your blades easily and quickly. 【Ideal Replacement Parts | Extend the Life of Your Sharpener】This set of replacement grinding wheels is specially designed for roller-mechanical home knife sharpeners. It is used when the original grinding wheel is worn. Please note that this kit contains only two replacement grinding wheels and does not include the rotating handle or magnetic base. It must be used with your rotary-mechanical knife sharpener.
